Abstract:

The agrometeorological weather station Dedelow was installed in 1991 by the Leibniz Centre for Agricultural Landscape Research (ZALF) e.V. and is managed by the research station of ZALF in Dedelow. The station is located within the municipality Dedelow, district Uckermark, state Brandenburg, Germany. Altitude in meter: 49 NN, Geographic latitude: 53,3665 N, Geographic longitude: 13,8030 E,Type: FMA 86. In 1991, data have been collected for: soil temperature in 20cm depth (°C); global radiation (J/cm²); relative humidity (%); air temperature, 20cm above ground (°C); air temperature, 2m above ground (°C); precipitation (mm); wind velocity (m/s); evaporation (mm). Data are saved by the logger of the station and are automatically transferred onto a PC which uses the Software MeteoWare Pro 1.02.

Method Description:

The data were obtained by an automatic measurement device, which is following the standards of the German Wheather Service (DWD). The basic measurement intervall for most of the parameters is 10 minutes. The data is aggregated later on to the following temperal levels (hour, day, month and year). The measurement series started in 1999. Elder values are available on request. (Spatial Scale Description: Water samples were collected at the point of maximum depth of the lake by means of a Ruttner bottle. Samples were collected at the following depths: 0, -2 m, -6 m, -10 m, -14 m, -18 m, bottom. Samples were kept refrigerated and transported to the laboratory where chlorophyll-a was determined following the method proposed by Strickland and Parsons (1968). Samples were collected monthly from june to october.)
